Even though water is considered flavorless, it does have a taste that can be influenced by many different factors. The taste of water is affected by the mineral content and compounds it contains. Tap water takes many routes to houses and is likely to taste different in other areas. Occasionally, the water will acquire minerals that enhance its flavor, or the pipes may cause a metallic taste. Other people's tap water may taste earthy or musty. The flavor of water is heavily influenced by the region, the water source, and the condition of the pipes.
What Could Be Causing the Bitter Taste in Water?
Typically, if your water tastes bitter, it could be because the pH is off. Additionally, high TDS (total dissolved solids) concentrations can cause bitter water. Hard water is characterized by a high TDS concentration. The corrosion of your home's pipes, which leads to an increase in copper or zinc concentrations, could also be a cause of bitter water. This may also contribute to a metallic taste, but there are also several other causes of a metallic taste in water.

What Can I Do to Make My Water Taste Better?
Ionized water filters can help adjust your water's pH level, thereby enhancing its flavor. If the cause of the bitter water is high levels of minerals, reverse osmosis filtration systems can remove the minerals causing the unwanted flavor. If your water is bitter because of higher TDS levels (which have no negative effect on human health), you can make it taste better by adding fresh fruits and herbs like lemon, mint, berries, and cucumber.
